His personality could be a blend of introversion and extroversion. In some situations, he would be like Sasuke, preferring to be alone and train or study. But when it comes to protecting his friends or family, he would show an extroverted side, being vocal and taking charge, much like Sakura when she is in a leadership role. He would also have a great respect for the ninja way, having been brought up hearing stories from his parents about their adventures and sacrifices.
Sasuke becomes more gentle. Usually he is cold and aloof, but with baby Sakura, he has to be soft. He shows more patience as he takes care of her needs, like when she cries and he tries to figure out what's wrong.
One possible plot could be that the baby boy inherits Sasuke's Sharingan. This leads to many challenges as they have to protect him from those who might want to use his power. Sakura, with her medical skills, tries to find a way to control or at least understand the implications of the Sharingan in a young child. Meanwhile, Sasuke trains the boy in self - defense, passing on his ninja skills in a more gentle way compared to how he was trained.
Since Sakura is a skilled medical ninja, the baby might also have an aptitude for medical ninjutsu. It could show an early interest in healing small wounds of its toys or pets. The baby might be able to combine the power of the Sharingan with medical ninjutsu, for example, using the Sharingan to better analyze internal injuries and then using medical ninjutsu to heal them more effectively.
He would probably be brave, just like his parents. Growing up in a world full of mythological creatures and challenges, he would have to be.
The baby might inherit Sasuke's brooding and determined nature. It could be very focused on achieving its goals, just like Sasuke was on his revenge mission. At the same time, from Sakura, it could get a sense of compassion. So it might be a complex character who is tough - minded but also caring towards others.
Sasuke's determination and focus can be passed on to their baby girl. He may set high standards for her in terms of her ninja skills (if in the Naruto - like universe). However, Sakura will be there to remind him that the baby girl also needs a childhood filled with love and play. Sakura's nurturing nature will ensure that the baby girl feels loved and cared for at all times, while Sasuke's more serious side will push her to be strong and capable.
Their relationship would likely become more intimate and committed. With a baby on the way, Sasuke would feel a greater sense of responsibility towards Sakura. He might be more protective and stay closer to her.
Their baby's personality would be a blend. Naruto is known for his loyalty and his big heart. The baby would likely have that same loyalty towards its friends and family. Sakura is a hard - working and confident woman. The baby could inherit her confidence and work ethic. It might also have Naruto's sense of humor, always able to make others laugh. At the same time, it could have Sakura's focus, being able to concentrate on tasks at hand. Overall, it would be a complex personality with a mix of the best traits from both parents.
I think the baby could be quite resourceful. Finnick was good at using his charm and skills to survive, and Katniss was always finding ways to get through difficult situations. So, the baby would likely inherit that ability to make the most of what's available. It would also probably be very protective of those it loves, having seen the sacrifices its parents made for each other and their friends.
The baby might be really competitive, getting that from both of them. Vegeta is always striving to be the best, and Goku loves a good fight. But it could also be really kind - Goku's a good - hearted guy, so that would rub off. Maybe a bit of a goofball too, like Goku.
